DESCRIPTION

These routines generate multiple reads from the mapped memory or device register. repcount data is copied from the device address, dev_addr,
to the host address, host_addr. For each input datum, the ddi_rep_get8(), ddi_rep_get16(), ddi_rep_get32(), and ddi_rep_get64() functions read 8 bits, 16 bits, 32 bits, and 64 bits of data, respectively, from the device address, dev_addr. dev_addr and host_addr must be aligned to the datum boundary described by the function.

Each individual datum will automatically be translated to maintain a consistent view between the host and the device based on the encoded information in the data access handle. The translation may
involve byte-swapping if the host and the device have incompatible endian characteristics.

When the flags argument is set to DDI_DEV_AUTOINCR, these functions treat the device address, dev_addr,
as a memory buffer location on the device and increment its address on the next input datum. However, when the flags argument is to DDI_DEV_NO_AUTOINCR, the same device address will be used for every datum access. For example, this flag may be useful when reading from a data register.

RETURN VALUES

These functions return the value read from the mapped address.

CONTEXT

These functions can be called from user, kernel, or interrupt context.

NOTES

The functions described in this manual page previously used symbolic names which specified their data access size; the function names have been changed so they now specify a fixed-width data size.
